(AP) -- The National Weather Service says the current storm system has added about a half-inch of rain, as expected.
Downtown Sacramento saw almost six-tenths of an inch in the last 24 hours. Up in the mountains, Sierra at Tahoe added another 5 inches of snow since Monday.
Up to 2 inches fell in the San Francisco region.
Meanwhile in Southern California, the first of a one-two punch of much-needed moisture has arrived, bringing light rain after unleashing downpours in the northern part of the state.
A cold front brought an intermittent drizzle to the greater Los Angeles area before dawn Tuesday.
The National Weather Service says a second storm expected to arrive later in the day will pack the heaviest showers. Between one and 2 inches of rain is expected at higher elevations.
The storms triggered fresh fears of mudslides in foothill neighborhoods beneath wildfire-scarred mountain areas.
A high-surf advisory is in effect along the Los Angeles County coast until 3 p.m. Wednesday.
Up to 2 inches fell Monday in the San Francisco and Sacramento regions, causing minor road flooding and scattered power outages.
